Title: High intensity radiation source
IPC: H01J61/28
Filed: 1975-06-12
Abstract: 1468137 Discharge lamp CANADIAN PATENTS & DEVELOPMENT Ltd 12 June 1975 [13 June 1974] 25247/75 Heading H1D [Also in Division H2] A high intensity stabilized long arc source of radiation (U.V., visible, I.R.) comprises a cylindrical arc tube transparent at least in part, with two electrodes on the axis, means for injecting cooling liquid to form a wall inside the tube, and provision for inert gas injection: a starting circuit initiates an arc between the electrodes stabilized by the gas and constricted by the liquid, with positive dynamic impedance. The liquid, e.g. water, is forced helically along quartz tube 22 from annular chamber 39 in the constrictor block attached to but insulated from anode 24 to exit at 33 in the cathode block 23, to be cooled and recirculated; anode and cathode copper blocks 24, 23 also have internal liquid cooling by passages 37, 38, 27, 28. Rare gas at a pressure above atmosphere may be injected at either end helically in the same rotational sense; in the Fig. the linear gas flow is opposite to the liquid, entering annular chamber 31 from supply 30 and leaving through duct 44 for recirculation. The D.C. arc is struck by a high voltage surge between thoriated W cathode 26 and similar anode surface 49, and is maintained temporarily by a capacitor chain until the current from the supply can be built up (Figs. 3-6, not shown). Between thoriated W-lined constriction 47 and the anode surface 49 the arc is not stabilized by gas and is forced to wander annularly by magnet 48. In an A.C. or D.C. arc both electrodes may be so equipped. In a second embodiment (Fig. 7, not shown), gas and liquid flow in the same direction, both being collected from an expansion chamber round the anode, which now has no separate constriction in front of it.

Title: Improvements in or relating to devices for delivering measured quantities of liquid
Inventor: SANDYS PETER ANTHONY
IPC: G01F11/32
Filed: 1949-10-03
Abstract: 674,139. Delivering measured quantities of liquid. BULL & CO., Ltd., R. H. Nov. 10, 1950 [Oct. 3, 1949], No. 25334/49. Class 106(v) A device for delivering measured quantities of liquid comprises a measuring chamber 1 with an inlet port 5 at the top and an outlet port 2 at the bottom, a valve member 8 adapted to move between two extreme positions to open and close the ports, a snap-acting mechanism 17 for operating the valve and an unobstructed air vent 11 which allows air to enter the measuring chamber when the valve closes the inlet port and is sealed from the measuring chamber when the valve closes the outlet port. The stem of the hollow valve member 8 passes upwards through a neck 12 on the cover of the measuring chamber and projects a short distance through a resilient waterproof membrane 16. A supply pipe 13 leads from an inverted bottle or other supply container to the neck 12 and carries a bracket 18 for the spring-loaded toggle mechanism 17. The toggle is operated by a cranked lever 25, of which one end 27 is moved by hand, or by the agency of the receptacle held under the outlet port, and the other end 26 engages the toggle lever 19 with a small amount of lost motion in a channel-section 30; stops 28, 29 limit the movement of the lever. The other toggle lever 20 is forked to engage slots on each side of a ferrule 24 on the valve stem and its length is such that the valve, in both its raised and lowered positions, is slightly inclined to the vertical axis, to assist in overcoming surface tension and to improve the liquid flow. A cam or suitable linkage (not shown) operated by the lever 25 may be provided to hold the toggle lever 20 against movement until the other toggle lever 19 is well past dead centre, in order to make the snap action more rapid and to prevent attempts to jam the valve in mid position, particularly in coin-freed apparatus. A spring-loaded plug on a spindle passing through the hollow valve, or a hinged flap, may be operated by the lever 25 to close the outlet port and prevent drips when the outlet port is sealed. In a modification, Fig. 4, the measuring chamber 31 has a limited sliding movement in a cover 33, a resilient membrane 43 forming a liquid-tight seal between the two parts, and, when the chamber is moved up by a receptacle pressed upwards against arms 57 and the valve 46 has straightened a spring-steel strip 52, the strip snaps rapidly upwards and opens the outlet port and closes the inlet port. To prevent turbulent flow, an air pipe 55 extends into a recess 56 in the valve, in both its raised and lowered positions. In either version, the measuring chamber may be of glass.

Title: Process for the production of steel ingots
IPC: B22D27/02
Filed: 1951-11-01
Abstract: 698,303. Casting processes. BOCHUMER VEREIN FUR GUSSTAHLFABRIKATION AKT.-GES. Nov. 1, 1951 [Nov. 10, 1950], No. 25586/51. Class 83 (i). [Also in Group XI] Cast steel ingots are cooled in the mould by first passing air or other gas through a cooling tube in the mould, gradually adding water to the air and finally passing water alone. The mould has the cooling tube 4 embedded in a loose dry sand layer 3, 10 to 40 mm. thick, adjacent a thin sheet-metal liner 1 which forms the inner face of the mould. The liner may be 1 to 4 mm. thick and becomes fused to the ingot. The molten steel may be produced in a " Siemens-Martin " or an electric furnace and in the mould may be subjected to the effect of low frequency induction currents insufficient to prevent cooling. This may be effected by passing the electric current through the cooling tube 4. The mould may be preheated by induction to 60-200‹ C. There may be a separate tube 4 in each of the sections A, B, C, as shown, so that the ingot can be solidfied from the bottom up by accelerating the cooling of the lower sections. The top section D has the same cross-section but the metal therein may be kept liquid by an arc electrode 7 to allow time for impurities rising from the centre of the ingot to be absorbed by a layer of slag.
